August 1, 2023 - DICA has received a patent for its ProStack Slot Lock Interlocking Cribbing Blocks.
Issued in late 2022, the patent (U.S. Patent 11,479,939), is for the slot-and-flange interlocking system.
Each block has a flat lower surface with downward lips at opposing ends of the lower surface.
When the blocks are stacked and pressure is applied, the blocks lock together, giving users the ability to safely gain cribbing height in unlevel conditions.
